noob question: function generators

[outofstepper]

Ok, this question might get a lot of eyes rolling and/or tears from laughter.. but here
we go..

Entry-level FG ($$$) vs. 555-based shoebox FG (~free)

used for learning / eventually debugging broken stuff.

So i won't be getting the freq range / stability / accuracy / ease-of-use of a pro unit.. understood..
but what I'm not quite so sure about is if I'm starting out with both hands tied behind my back
because of any (obvious?) limitations I might not be aware of.

Thoughts?

and thanks!

What do you have to lose? If you think the free 555 shoebox will do, then start with it? While using it you can save more money to buy a real generator, and learn things the hard way. Aka the school of hard knocks.

As long as you can get a decent sine wave out of the shoebox parts then I second the post above.

One should simply start off with building his/her own "555" based Sig Gen, thy learns more that way

How about something designed for the job, like XR2206? Do they still make them? Or are there any modern alternatives?

In fact, as a pure electronics hobbyist, I'm missing a function gen too! Maybe we could design one together?

Before I bought my Instek I was considering this: http://www.electronics-diy.com/store.php?sel=kits&sub=function_generator
Only $40.

I ordered and put this kit together to mess around till I decide on a proper FG.

Works for me right now!

Thanks guys.
That kit from electronics-DIY looks interesting and I'll likely pick it up.
 -- two minor points though (not complaining!), the freq range selector
is pcb mount dip switch so if I wanted to put this in a nice case I'd have to find a selector switch
(I assume only 1 of the four pins goes high to select).  Second, the freq counter kit is nice too but
resolution in 10Mhz steps.

Beggers being choosers?  Maybe. 

Thanks again!

Before you do take a look at this one:

I am not sure if there is a kit, but it is very well documented.
Look under Project Details on the Right below the clock.
